First, substitute the values of the variables into the equation:
2x+(3)(6)=36
Then, you must simplify,
2x+18=36
Then, you must factor out 18 to leave x and its coefficient alone on one side of the equation:
2x+18-18=36-18
Then you must simplify the equation and divide by 2 on both sides of the equation to factor out the coefficient:
2x/2=18/2
Then you will simplify and you will find the value of x:
x=9
Answer:
if Im not mistaken it is 2
Step-by-step explanation:
2! Is the same thing as 2*1 and 2*1 is 2, so technically for factorials the higher in number you get you have to multiply all the numbers going back to one
The question is not clear but I will solve it for all the possible conditions.
If cosФ = - √37 ÷ 6
Which means,
Adjacent = - √37
Hypotenuse = 6
This is not possible because hypotenuse cannot be smaller.
If cosecФ = - √37 ÷ 6
Which means,
Opposite = 6
Hypotenuse = - √37
Using Pythagoras theorem,
Adjacent = (Hypotenuse)² - (Opposite)²
Adjacent = √{(- √37)² - (6)²}
Adjacent = √{(37 - 36}
Adjacent = √{(1}
Adjacent = 1
Now we have all the three sides of a right triangle, therefore, we can find out the value for cotФ.
That is;
cotФ = adjacent ÷ opposite
cotФ =
8 tenths is equal to 8/10, what is equal to 0,8. You can calculate the distance by multiplying 0,8 with the 1,6 mile course. That gives you 1,28 miles. Doing that for Sheila’s 9 tenth (0,9) gives you 1,44 miles. That means she swam 1,44-1,28 = 0,16 miles more than Simon.
